30 ILLINOIS BIOLOGICAL MONOGRAPHS [498 



Capitate hyphopodia alternate or unilateral, about 50-80/x apart, 

 head cell ovoid or angular, 20 x 14/i., stalk cell 10 x 14/u, long. Mucro- 

 nate hyphopodia scant, bottle-shaped. Mycelial setae none. Perithecial 

 setae numerous, 20/t, straight or slightly curved, rigid, dark, about 85/a 

 long, apex obtuse. 



Perithecia 170/t, black. Asci evanescent. Spores 4-septate, dark, 

 constricted, somewhat pointed at ends, 50 x 14/t. 



On Ocotea leucoxylon (Sw.) Mez. 



Jajome Alto, July 17, '15, 8428 (type). 



Eesembling M. molleriana but differing from it in number, length 

 and character of the perithecial hairs and in mycelial characters. Usually 

 densely overgrown with conidial forms. 



34. Meliola compacta Earle 



Bull. N. Y. Bot. Gard. 3 : 306, 1905. Collected by Heller, No. 6217, 

 "on Crossopetalum pollens." 



35. Meliola miconiae sp. nov. 



Colonies epiphyllous, circular, 2-5 mm. in diam., very sharply lim- 

 ited, black, smooth. Mycelium forming a close network of threads 

 mainly with opposite branches, Ifi in diameter. 



Capitate hyphopodia alternate or irregular, not crowded, about 30/i 

 apart, head cell pyriform, irregular and angular, often bent, the basal 

 cell 7-9/1 long. Mucronate hyphopodia not seen. Mycelial setae none. 

 Perithecial setae very inconspicuous, few, about 3-10, straight or 

 slightly curved, or coiled, 30-85 x 10/i. Tip obtuse. 



Perithecia 170-225/ti, slightly rough with conic protuberances. Asci 

 four-spored, soon evanescent; ascospores 4-septate, brown, slightly con- 

 stricted, obtuse, 44-47 x 17/i. 



On Miconia prasina (Sw.) P. DC. Fig. 29. 



Las Piedras, Aug. 12, '15, 9366 (type). Las Marias, July 10, '15, 

 8160. 



This species is quite distinct from the two others found in Porto Rico 

 upon Melastomataceae. Its very distinct colony is readily recognizable 

 by the naked eye as a distinct form. 



36. Meliola tbiumfettae sp. nov. 



Colonies epiphyllous, punctiform, 1-3 mm. in diam. Mycelium 

 forming a close network of crooked threads which branch irregularly, 

 6/x in diameter. 



Capitate hyphopodia small, alternate or irregular, not crowded,
